[Elecraft] KX2 Battery Question

[Tim McDonough N9PUZ]

I have a "new to me" KX2 along with the internal battery and charger. 
Inside the KX2 battery compartment, is there supposed to be any sort of 
insulating sheet or pad covering the circuit board?

There was nothing inside mine when I opened it and my first thought is 
that even though it is insulated the battery pack shouldn't lay right on 
the circuit board above. I don't want to chance damaging the radio.
